改性LLDPE高速挤出绝缘料的研制 总被引:2,自引:0,他引:2
为发展我国的通信事业,成都电缆厂等单位先后引进了全塑市话电缆高速挤出生产线.由于我国各石化总厂目前尚无生产高速挤出聚乙烯电缆绝缘料的专用树脂,因此,所需高速料大量依靠进口.为尽快实现高速挤出聚乙烯绝缘料的国产化,我们对国产LLDPE进行共混改性研究,研制了改性LLDPE高速挤出绝缘料. 相似文献

A series of UV-curable polyurethane acrylate resins based on hydroxy-terminated polydimethylsiloxane (PDMS) soft segments with different molecular weights and various diisocyanate hard segments were synthesized. The products were obtained by employing direct-addition polymerization techniques in a nonsolvent system. The structures of the final products were elucidated by IR and 1H-NMR. The fundamental and physical properties of this type of UV-curable material, the effects on properties by varying the molecular weight of PDMS or the type of diisocyanates, and the effect of using various reactive diluents were widely studied. This resin possessed good optical, electrical insulating, and adhesive properties. The mechanical strength of UV-cured films corresponds approximately to the ratio of hard segments within these material and the dielectric insulating properties correspond to the chain length of PDMS. 相似文献

Conclusions Studies were made of heat insulating aluminosilicate products produced by certain companies. The articles are divided into four groups. It is found that within the limits of any one group there is a substantial spread in the properties: strength, apparent density, and temperature of deformation.The main form of raw material for producing insulating products is kaolin, including beneficiated kaolin. Out of 22 specimens investigated eight contained no more than 0.64% Fe2O3, which is important for the service of the products in reducing atmospheres; the semiacid and kaolin products contained iron oxide varying in the range 1.0–1.5%.The use of pure kaolins and low-ash combustible additives in the production of insulating refractories contributes to the production of refractories with a low concentration of fusible impurities.Translated from Ogneupory, No. 8, pp. 57–59, August, 1972. 相似文献
